I have 2 12" Fi Q's and im probobly going to order a subthump box for them, because I hear subthump makes one of the best prefab boxes for Camaros and Trans-Ams. However, these boxes only have a total of about 2 cu. ft. and after diplacement that would only leave me about .85 cu. ft. per sub. These boxes dont take up the whole rear well though, so if you guys think it would be worth it, I could cut out part of the bottom of the box and add some space down there.

Thanks,

Ben

I think you'll be okay but you can try using some polyfill.

If you are going to cutout the bottom...why not just go with a custom FG box?

Ive never made anything big with fiberglass, Im afraid it wouldnt turn out very well.

It's pretty easy for something like this, there's a few build logs here that show exactly what you're trying to do

sweet, ill do some research and see if I think i can do it.

Personally I don't like subthump boxes at all, nor would that be enough space. I like the recommendations of building your own.

There's only one way to get better! Plus, you'll be a lot more satisfied with the end result if you DIY it.

Thanks guys, Ive been researching fiberglass, and ive decided to build it myself for sure. But I cant decide if I want to make alot of it out of wood with the top fiberglass, or make the whole thing out of fiberglass, what do yall think?
